Solution:
Illiterate people are a liability to the economy.The population's quality ultimately determines the growth rate of the nation. People who are illiterate and unHealthy become a financial liability because they cannot utilise land and capital productively or add value to any economic activity. An illiterate and diseased population is a liability to the economy. They have a low or no income. Technology is underdeveloped, resulting in a country that is underdeveloped or impoverished. Productivity has decreased. In life, they have not been successful. They eventually weigh down the whole economy and become a liability for the entire nation.
